SYSTEM OVERVIEW

The San Rafael Sanitation District (SRSD or District) is a sanitation district of the County of Marin

formed in 1947 under Division 5 of the California Health & Safety Code. It serves the southern two-

thirds of the City of San Rafael, in the Central San Rafael area south from the top of Puerto Suello

Hill, and the adjacent unincorporated areas. The District is administered by a three person Board of

Directors comprising two members of the San Rafael City Council and one member from the Marin

County Board of Supervisors.

The District provides wastewater collection and transportation service over its entire collection

system area, which is 12.75 square miles consisting of 134 miles of gravity sanitary sewer piping, 32

wastewater pump stations, and 13 miles of force main piping. The District’s flows are ultimately

conveyed to the Central Marin Sanitation Agency (CMSA) wastewater treatment plant, located at

1301 Anderson Drive in San Rafael, CA. SRSD, the Ross Valley Sanitary District, and Sanitary

District No. 2 of Marin County have a joint powers agreement in place with CMSA for the treatment

of their wastewater.

SRSD’s mission is to responsibly collect and transport wastewater from its customers to CMSA for

treatment, utilizing cost effective, environmentally sound, and safe practices. It has implemented

numerous processes, as described herein, in order to better maintain its collection system and

accomplish this mission.

ELEMENT 1 - GOALS

SRSD has assembled this Sewer System Management Plan (SSMP) pursuant to the State Water

Resources Control Board (State Water Board) Order No 2006-0003-DWQ and the San Francisco

Bay Regional Water Quality Control Board’s (RWQCB) development guide dated July 2005. The

goals of the SSMP are to accomplish the following:

Properly manage, operate, and maintain all parts of the wastewater collection system.

Provide adequate capacity to convey peak flows.

Minimize the frequency of Sanitary Sewer Overflows (SSOs).

Mitigate the impact of SSOs.

Meet all RWQCB and all State Water Board requirements for SSMP development, auditing, and

updating, as well as requirements for SSO reporting.

Implement recurring, proactive maintenance of the collection system to remove roots, debris,

and fats, oil, and grease (FOG) in areas prone to blockages that may cause sewer backups or

SSOs.

Exceed citizen expectations when responding to their calls regarding sewer problems.

Work cooperatively with local, state, and federal agencies to reduce, mitigate impacts of, and

properly report SSOs.

ELEMENT 3 - LEGAL AUTHORITY

SRSD was formed in 1947 under the California Health and Safety Code, Section 4700, Division 5,

Part 3, Chapter 3, County Sanitation Districts. With this legal authority, the District Board of

Directors passes ordinances and resolutions to govern all aspects of the District’s collection system

from the point of connection with the side sewers (laterals) to the headworks of the CMSA treatment

plant.

Laterals between the main sewer and the building are privately owned and maintained, the District

has no ownership or maintenance responsibility therefor, per District Ordinance No. 54.

3.1 Prevention of Illicit Discharges

Regulations preventing illicit discharges into the District’s sanitary sewer system are included in

the Standard Specifications 2007, Part B, Section 4-02, as well as the Districts Standard

Specifications for Side Sewers and Laterals 2007 Section 1-09. These sections list wastes that

are prohibited from entering into the system. They also have requirements to control inflow and

infiltration (I/I) by prohibited roof leaders, surface drains, rainwater, storm water, seepage,

cooling water, or unpolluted industrial process waters from entering the system.

The District’s Standard Specifications were adopted in Resolution 07-940 on June 11, 2007.

3.2 Design and Construction of New and Rehabilitated Sewers and Connections

The San Rafael Sanitation District Standard Specifications and Drawings 2007 provide

requirements for proper design and construction of new and rehabilitated sewers and

connections. Design requirements are included in Part B of the Standards, Construction

requirements are included in Part C and Part D of the Standard Specifications.

District Ordinance No. 56, adopted March 1, 2006, provides the manner and charges for

connection to District facilities and penalties for violation thereof.

3.3 District Access

The District’s Standard Specifications 2007 include an annexation policy, a right of way policy,

and a condemnation policy, Section 1-03, 1-05, and 1-06 respectively. These sections provide

the District with legal authority to obtain easements and maintain access for maintenance,

inspection, or repairs of the public sewers in its service area.

Laterals are owned and maintained by the property owners, as previously stated.

3.4 Limit FOG and Other Debris

To limit the discharge of FOG into its system, on October 4, 2006 the District adopted the

provision of CMSA’s FOG Program with SRSD Resolution No 06-930. The District and CMSA

have entered into a written agreement; the “Fats, Oils & Grease (FOG) Control Program

Agreement” dated May 10, 2006. The agreement provides for CMSA to develop implement,

manage, and administer a FOG source control program within the District’s service area. A copy



of CMSA’s Conformed Fog Ordinance, SRSD Resolution No 06-930, and the agreement

between the District and CMSA is included in Appendix F.

The District’s Standard Specifications 2007, Part B Section 4-02 and the Standard Specifications

for Side Sewers and Laterals 2007 Section 1-09 list prohibited wastes and limit discharge of

FOG and/or debris that may cause blockages, such as sludge, rags, garbage, and any other solid

or viscous substance capable of causing obstruction to the flow in sewers or causing other

interference with the proper operation of the sewage works.

3.5 Enforcement of Violations

California Health and Safety Code, Section 4700, Division 5, Part 3, Chapter 3, County

Sanitation Districts provides SRSD with the legal authority to enforce any violation of its sewer

ordinances. Also, under the Joint Powers Agreement between CMSA and the District, CMSA

issues Wastewater Discharge Permits and has the legal authority to enforce violations.

Laterals are owned and maintained by the property owners and the District relies on the County

of Marin, Environmental Health and Services to enforce private lateral SSO’s and septic tank

violations.

3.6 Installation, Testing, and Inspection of New and Rehabilitated Sewers

Requirements for proper installation, testing, and inspection of new and rehabilitated sewers are

included in the San Rafael Sanitation District Standard Specifications and Drawings 2007.



ELEMENT 4 - OPERATION AND MAINTENANCE PROGRAM

4.1 Collection System Map

The District maintains geographic information system (GIS) maps, using MapServer.

MapServer displays streets, contours and elevations, wastewater pump stations, sewer pipes,

sewer force mains, sewer manholes and rodholes, air release valves, building footprints, parcels,

easements, orthophotos, scanned construction plans, and other City and District facilities. SRSD

partially pays a GIS Analyst employed by the City of San Rafael to support and provide

mapping, GIS, and database support for the District.

MapServer allows features, such as manholes and pipe segments, to accept linking of additional

data, such as inspection logs, pictures, CCTV videos, etc. Figure 4-1 below shows a typical

District MapServer screen display.

Figure 4-1 MapServer Screen Display

The District has included a sewer maintenance management application in MapServer, where it

enables the District to track its daily maintenance activities and sewer overflows. The District

uses MapServer to schedule, track, and adjust its maintenance operations as well as to identify

any “hot spots” in the system. Figure 4-2 shows a closer look at the type of maintenance reports

that MapServer allows the District to generate and utilize.



Figure 4-2 MapServer Report

The District updates the GIS map data based on routine maintenance performed throughout the

year and any new construction or rehabilitation work performed.

4.2 Preventative Operation and Maintenance Activities

In 2008 the District began a 3-year sewer pipe cleaning program, where all gravity sewer pipes

are scheduled to be cleaned at least once every three years. Scheduled cleaning of the gravity

sewers is based on a District maintained list of sewer lines, with some lines established as

needing more frequent cleaning than others to minimize the possibility of a SSO.

Gravity sewer lines with FOG related issues, or “hot spots”, are cleaned more regularly with a

hydro flusher. SRSD schedules cleaning of “hot spots” a minimum of twice per year.

The gravity sewer lines that have had a history of stoppages due to roots, rags and debris are

maintained with a power rodder. A hand rodder is used on sewer lines where little or no

mechanical equipment access is available.

In addition, the District’s goal is to maintain the following schedule with its preventative

maintenance:

All forcemain valves to be exercised annually.

All pump station valves to be exercised quarterly.



Annual preventive maintenance to be performed on all pump station pumps, motors, and

control cabinets.

Annual preventive maintenance and load bank testing to be performed on all pump

station emergency generators, and mobile generators.

Pump station wet wells to be inspected and cleaned annually.

Air relief valves to be inspected and cleaned twice per year.

Chemical injection systems to combat odor and corrosion to be inspected and calibrated

weekly. Samples to be taken to monitor hydrogen sulfide levels twice weekly.

All pump stations to be checked three (3) times per week

The pump station inspections are typically performed on Monday, Wednesday, and Friday to

verify that all control panels, pumps, and motors are functioning properly. In addition to obvious

and/or immediate issues that may be observed, maintenance crews check pump run times

excessive pump wear, wet well debris accumulation, and an increase in utility bills. These issues

will typically indicate that higher flows are entering the station, or that further assessment and

repair or maintenance may be required at the station.

SRSD uses its sewer maintenance application in MapServer for tracking maintenance activities,

as previously mentioned. MapServer allows crews to log the maintenance they perform for all

their daily activities. Each structure has its own identifiable tag, and is mapped on the GIS based

platform. Tracking routine maintenance with its sewer maintenance application helps the District

to prioritize pipelines that may require inspection or repair. Routine maintenance can often

reveal evidence of collection system deficiencies. Crews may notice an increased difficulty

maintaining a pipeline, which would indicate a high priority to perform inspection.

4.3 Rehabilitation and Replacement Plan

Through tracking of maintenance activities with its sewer maintenance application, including

frequency of calls and types of calls from the public, and routine inspection of its facilities, the

District prioritizes system deficiencies to implement short-term and long term rehabilitation

actions in order to address them.

The District’s short term goal is to address pipes at risk of collapse or prone to more frequent

blockages due to pipe defects and capacity, and pump stations with frequent maintenance issues

or capacity issues.

The District’s long term goal for preventative maintenance is to replace all of its gravity sewers

on an 80 year cycle.



A. Inspections

CCTV inspection is performed for the District’s sewer mains that have had backup or

overflow history. Locations with multiple incidents are given first priority. The inspections

are used to generate a list of priority spot repairs, or sewer main rehabilitation projects.

SRSD contracts most CCTV work. However, the District has a small lateral camera for

shorter sections of pipeline and a pipe locater to identify gravity sewer problems and locate

structural deficiencies, such as broken pipe, offset joints, etc.

The District’s short term goal is to perform CCTV inspection of ten percent of its sewer

mains and all gravity sewers within 750 feet of surface water in a five year program. This

program will provide information on the current condition of the sewers for the District’s

80-year life cycle program. This initial collection of pipeline inspections will provide

information for the District’s long term goal, which is a complete survey of all gravity

sewers within its service area. The long term goal also includes linking all of the CCTV

survey information including audio and video digital data to each pipe or manhole segment

in the GIS database using MapServer, as previously described. Each manhole and pipe

segment is individually located and can accept linking of additional data, such as the CCTV

survey.

The District has plans to develop an ongoing smoke test procedure to determine illegal

connections to sewer mains.

The Districts criteria for linking inspection data to pipes and manholes in MapServer include

the following:

1. Pipes:

All pipe segment inspection data will be linked to the appropriate pipe segment on the

District’s GIS.

All pipe segments will be individual digital files, with no continuous files through

manholes or structures.

All pipe surveys to be performed in the direction of flow, where feasible.

Condition survey rating will be calculated on each separate pipe segment in accordance

with standard evaluating procedures, and linked to GIS segment.

2. Manholes:

All manhole inspection data will be linked to the appropriate manhole on the District’s

GIS.

Inspected manhole X, Y, Z coordinates in the State Plane coordinate system, and

latitude and longitude will be recorded.



A sketch of each inspected manhole showing location of all pipes using a clock face

with north facing at 12 o’clock will be created. The depth, size, and material type of all

pipes will be indicated.

Digital photographs of inspected manholes will be taken above and below ground with

condition survey and condition assessment.

B. Capital Improvements Plan

SRSD is a special District with fiscal and administrative autonomy. The District invoices its

customers and obtains revenue to fund its operations utilizing property tax statements. Sewer

service fees and property taxes appear on Marin County Property Tax Statements. The

District also obtains revenue from connection fees and interest generated from its savings.

The user fees charged for residential dwellings and businesses are calculated differently.

Residential properties are assigned an Equivalent Dwelling Unit (EDU) based upon the

actual dwelling units (units) permitted on the property, regardless of occupancy, as

determined by the Marin County Assessor Office records. Business fees are calculated

individually based on the volume and strength (cost to treat) of the sewage measured in

EDUs. In the fiscal year 2013/2014, SRSD began increasing its rates for a period of five (5)

years to accelerate the replacement of sewer pipelines and the rehabilitation of the pump

stations.

The District allocates adequate resources for the operation, maintenance, and repair of its

collection system. In general, the District plans and budgets for the following expenses:

Maintenance and Operation

Sewage Treatment (Paid to Central Marin Sanitation Agency)

Capital Improvements

Rehabilitation and Repairs

Emergency Expenses

Reserves

The District operates under a fiscal year budget cycle beginning July 1 and ending June 30.

Revenue and expenditures for 2014/2015 and the District's Capital Improvement Program

Schedule through 2018/2019 for gravity sewers and 2020/2021 for pump stations and

forcemains are summarized in Appendix H. This Capital Improvements Program Schedule

includes a time schedule for implementing the short and long term capital improvement

projects, as well as estimated budgets and estimated available funds.

SRSD contracts with the City of San Rafael for its employees, as previously shown in

Element 2. District staff are responsible for administration, engineering, planning, and sewer

system operations and maintenance. The District currently contracts with Maher



Accountancy for financial management and accounting. The District also has agreements in

place and pays CMSA for treatment of its wastewater, as well as source control and

regulation of the FOG program, which is further described in Element 7.

4.4 Training

SRSD has a safety training program that complies with OSHA mandates and established work

safety procedures developed by the Department of Public Works (DPW) for the City of San

Rafael. The DPW/SRSD Safety Committee identifies appropriate safety trainings needed per job

classification.

On the job training and mentoring by experienced workers has been the main source of

occupational education for the operations and maintenance staff. Seminars, classes, and

equipment demos also help staff stay current with the best available practices and equipment in

the wastewater industry.

SRSD encourages the pursuit of occupational education such as California Water Environment

Association (CWEA) memberships, classes, seminars, and certifications. The District provides

funding to interested personnel for obtaining this training.

It is the goal of SRSD to have well-educated and competent staff that are able to serve the

public, eliminate SSO’s and provide a safe, well maintained and efficient sanitary sewer system.

4.5 Contingency Equipment and Replacement Inventories

The District maintains a number of contingency vehicles and equipment for emergency use, as

4.6 Outreach to Plumbers and Building Contractors

SRSD has made available its Standard Specifications and Drawings and its Standard

Specifications for Side Sewer Laterals to plumbers, building contractors, and the public. These

Standards provide plumbers and contractors with guidelines and requirements for construction,

as well as testing requirements. Much of the District’s outreach program consists of on-site

interaction between District inspectors and plumbers and Contractors, where District staff can

educate them, in multiple languages, on the District Standards, requirements, and acceptable

practices.

The District provides information about the proper practices for preventing blockages in private

laterals to the public via newsletters, which are mailed to its customers periodically and are

available on the Internet. Recent newsletters address issues with FOG and “flushable” wipes that

may cause maintenance issues and SSOs. The District has encountered issues with rags and

wipes creating blockages in the sewer pipelines in the vicinity of schools, so it has begun

outreach to the San Rafael schools in its service area. It has sent a newsletter, specifically

targeting the public, private and day care schools, educating them of the proper handling of the

“flushable” wipes. The District has developed its webpage under the City of San Rafael website,

which encourage the use of proper practices for preventing blockages. The District also

distributes magnets encouraging residents of proper disposal of cooking oils and grease in the

trash.



ELEMENT 5 - DESIGN AND PERFORMANCE PROVISIONS

The District has developed the following Design and Construction Standards:

San Rafael Sanitation District Standard Specifications and Drawings, 2007

These Standard Specifications and Drawings are available to the public at:

http://www.usspecbook.com/files/specs/san-rafael-sanitation-district-california.pdf

San Rafael Sanitation District Specifications for Side Sewers and Laterals, 2007

These Specifications for Side Sewers and Laterals are available to the public at:

http://docs.cityofsanrafael.org/PubWorks/Sanitation/SRSD_2007_Specs-

Side_Sewers_Laterals.pdf

5.1 Standards for Installation, Rehabilitation, and Repair

The District’s minimum design and construction standards and specifications for the installation

of new sewer systems and for the rehabilitation and repair for existing sewer systems are

included in the above referenced Standard Specifications and Drawings and Specifications for

Side Sewers and Laterals. These Standard Specifications and Drawings are appropriate and

relatively up to date.

5.2 Standards for Inspection and Testing of New and Rehabilitated Facilities

The District’s procedures and standards for inspecting and testing the installation of new sewers,

pump station, and other appurtenances; and for rehabilitation and repair projects are included in

the above referenced Standard Specifications and Drawings and Specifications for Side Sewers

and Laterals.

http://www.usspecbook.com/files/specs/san-rafael-sanitation-district-california.pdf



ELEMENT 6 - OVERFLOW EMERGENCY RESPONSE PLAN

The District has developed the following procedures for responding to SSOs. The purpose of the

Overflow Emergency Response Plan is to provide guidance to maintenance crew personnel when

responding to an SSO, and to ensure that all SSO responses are handled efficiently, effectively, and

in accordance with regulatory requirements. This procedure is applicable to all overflows of the

sewage collection system.

In general this element covers the following categories:

SSO Notification

SSO Response and Impact Mitigation

SSO Reporting

6.1 SSO Notification

During normal business hours (Monday through Friday, 6:30 AM to 2:30 PM) the Sewer

Maintenance crew responds to all reports of SSOs. During business hours crews are dispatched

immediately to respond to any reported SSO. Phone calls during normal working hours

regarding problems with the collection system are typically received at the Corporation Yard and

the nearest sewer maintenance crew is then dispatched to the scene via radio or cell phone.

After normal business hours, there is always one field crew member available to respond to

sewer system emergencies. This individual carries a pager (415 451-0388), and takes the

emergency response vehicle home each night so he or she can respond directly to the scene of

the reported problem.

After-hour sewer system problem calls are often first received by the Police Department

dispatchers, who then contact the after-hours contractor for collection system sewer problems. If

someone calls the published sewer maintenance phone number outside of business hours, a

recorded message refers them to the Police Department emergency phone number for assistance.

The ability for a caller to be able to talk to a live person at all times significantly reduces the

possibility of a missed call or a misunderstanding about the nature of a problem.

The District’s Pump Stations are equipped with high water level and pump alarms that will alert

the Corporation Yard if an alarm is received during working hours. The alarms will alert the on

call pager.

When a call reporting an SSO is received, District staff should advise the caller to stop the use of

water in their building/home. DO NOT admit or deny liability. District staff should attempt to

obtain the following relevant information from the caller:

Time and date call was received

Specific location of the overflow, address or cross streets



Description of problem

Time possible overflow was first noticed by caller

Caller’s name and phone number

Other relevant information, such as: was overflow observed from the cleanout at the

property line, or a manhole in the street? Were the drains in the home were running

slowly prior to the overflow? If so, what time was this observed?

6.2 SSO RESPONSE AND IMPACT MITEGATION PROCEDURES

After receiving notification of the SSO via a phone call or an alarm, maintenance staff responds

as quickly as possible. The District’s goal during working hours is to provide a 15 minute

response time for all sewer overflows and sewer calls. The District’s goal for responding to

after-hour emergency calls is to provide a 30 minute response.

District Maintenance staff will perform the following steps, as required to respond to and

mitigate the impact of all SSOs:

Investigate and assess the problem

Reduce or stop the overflow at its source

Contain the overflow

Public safety and traffic control

Final volume assessment

Cleanup

Receiving water sampling

Maintenance staff will complete the SSO Field Report Form included in Appendix A as they

complete the above steps and provide the completed form to the Maintenance Supervisor for

SSO reporting to the appropriate agencies.

A. Investigate and Assess the Problem

Maintenance staff responding to an SSO should perform the following:

1. Locate the SSO by address, cross street and point of overflow (i.e. manhole, cleanout,

pump station, broken pipe).

2. Note the time of arrival, as well as the time the notification call was received.

3. Identify yourself to the property owner who called for service, if applicable, and briefly

explain what you will be doing. Advise them to stop the use of water that will enter

drains or flushing toilets in their building/home. Do not admit or deny liability.



4. Take digital photos and/or video to document the conditions and the flow.

5. Determine the magnitude of the SSO and attempt to estimate the flowrate. The figures

and tables included in Appendix B, prepared by the CWEA, may be used to estimate the

SSO flowrate.

6. Determine the Category of the SSO:

a. Category 1 SSO – Defined as discharges of untreated or partially treated wastewater

of any volume resulting from the sanitary sewer system failure or flow condition

that reaches surface water and/or reach a drainage channel tributary to a surface

water, or that reaches the storm drain system and is not fully captured and returned

to the sanitary sewer system.

b. Category 2 SSO – Discharges of untreated or partially treated wastewater greater

than or equal to 1,000 gallons resulting from the sanitary sewer system failure or

flow condition that does not reach a surface water, a drainage channel, or the storm

drain system unless the entire SSO volume discharged to the storm drain system is

fully recovered and disposed of properly.

c. Category 3 SSO – All other discharges of untreated or partially treated wastewater

resulting from the sanitary sewer system failure or flow condition.

7. Contact the Maintenance Supervisor immediately for any of the following:

a. The SSO is a Category 1 or Category 2. The Maintenance Supervisor will notify

appropriate agencies, if required.

b. Additional staff and/or resources are needed.

c. The SSO causes property damage or flooding in a structure.

d. The SSO constitutes an imminent danger to the public or the environment.

B. Reduce or Stop the Overflow at the Source

Identify the cause of the problem. In some cases, such as in flat areas, the cause of the

overflow may be located a considerable distance downstream of the SSO. During large

storms, overflows may be related to excessive inflow and infiltration (I&I) and it may not be

possible to stop the flow until flows recede.

The cause of the overflow will typically be in/at a sewer main, side sewer/lateral, or Pump

Station.

1. Sewer Mains

a. Check Flow in the manholes. Blockage or obstruction between manholes will

typically cause surcharging upstream and very little flow downstream.



b. Remove the blockage and restore flow.

c. If removing the blockage is difficult, contact the maintenance supervisor. Additional

maintenance staff assistance, bypass pumping, and/or the use of a private

contractor/vendor may be required. See Appendix D for a list of emergency vendor

contact information.

d. If necessary, add the line segment to cleaning schedule, change cleaning frequency,

or change cleaning method, inspect by video camera, or report on the need for any

correction measures.

2. Side Sewers/Laterals

a. Side sewers/laterals are privately owned and are not the responsibility of the

District.

b. If flow is normal in the main line, then it should be assumed that the obstruction is

either in the lateral or in the building plumbing.

c. If the obstruction is in the lateral, the homeowner should be notified that the

obstruction is within the portion of the piping that they are responsible for advised to

contact a plumber for assistance.

d. If the overflow is inside or under a building and caused by an obstruction in a main

line, the District Maintenance Staff will perform the following:

i. If necessary, evacuate the affected people.

ii. Advise people to keep others and pets out of contaminated areas and not to

track contamination into other areas.

iii. Stop or reduce flow into the building by removing the cleanout cap.

iv. Clear the obstruction and contain and recover as much of the overflow solids,

liquids, and wash-down water (outside of the building) as possible.

v. Notify the maintenance supervisor.

vi. Maintenance supervisor will follow procedures for reporting a sewer backup

to the insurance carrier and local adjuster, in Accordance with Appendix E.

The District will give the effected party a list of recommended emergency

cleaning vendors that they may contact, see Appendix E.

vii. If necessary, TMB Environmental & Loss Management will be contacted.

viii. If necessary, temporary lodging arrangements will be made for the residents.

3. Pump Stations



In addition to the SSO Emergency Response Plan, the District is in the process of

developing standard operating procedures (SOPs) for emergencies at each of its 32

pump stations. Each pump station has different operations and procedures that must be

performed by maintenance staff in an emergency. The pump station SOPs will provide

staff with guidelines for emergency procedures at each specific station.

C. Contain the Overflow

Make every attempt to contain the overflow before it reaches any drainage ways or surface

waters.

1. Possible options for containing the overflow (outside of buildings) may include:

a. Build dike with hay bales or sandbags and plastic sheeting.

b. Build earthen berm or dig a trench.

c. Use pipe plug to plug storm drain/use plastic sheet over inlet to stop flow.

d. Sand bags in gutters

e. Dry sweep

f. Vactor truck

g. During dry weather, the storm drain system can be used to contain the overflow if it

can be plugged downstream and water can later be returned to the sanitary sewer

system.

2. For overflows into storm drains or drainage ditches (during dry weather only):

a. Determine downstream endpoint of the overflow in the drainage system.

b. Plug all affected storm drain outlets

c. Hydroflush the affected mains and pump/vacuum all water from the storm drain into

the sanitary sewer system.

After containing the flow, take digital photos or video to document the conditions.

D. Public Safety and Traffic Control

Maintenance staff will place warning signs and provide traffic control, as required, for

public and staff safety.

1. Warning Signs:

a. SRSD maintains an inventory of Raw Sewage Warning signs and barricades for

posting at recreational areas or locations where the public may potentially contact



wastewater that was spilled into the storm drain system, drainage channels, creeks,

storage ponds, or lagoons downstream of the spill.

Signs are stored in the District Maintenance Shop, in the black file cabinet next to

the TV, lower shelf.

b. For Category 1 and 2 SSOs: Signs warning the public of a sewage release should be

posted in the affected area. Signs should include, at a minimum, the wording of

“raw sewage”.

c. Document where signs are placed so every sign can be retrieved after cleanup.

d. Coordinate with Rebecca Ng at the Marin County Environmental Health Services

(EHS) as to exact placement of the signs.

e. Warning Sign Removal: In critical areas such as creeks and parks, warning signs

should remain posted until County Health or Regional Board staff authorize their

removal, and until receiving water sample results indicate background levels (levels

as determined by upstream samples) have been attained.

2. Traffic Control

a. Traffic control may be required to prevent wastewater from being tracked to non-

contaminated areas and to protect the maintenance crew.

b. Provide traffic control per Caltrans Standard Specifications.

c. If necessary, contact the Maintenance Supervisor who may coordinate with the

Police or private Contractors for additional assistance.

3. Public Notification

a. For Category 1 and Category 2 SSOs, coordinate with Rebecca Ng at the Marin

County EHS whether or not the press needs to be notified of the spill.

b. If the press needs to be notified, contact the District Manager/District Engineer,

Doris Toy at 415 485-3484 or at the numbers listed in Section 2.1.

c. The District Manager/District Engineer will contact the Board members and the City

of San Rafael, Department of Public Works for Category 1 SSOs.

E. Final Volume Assessment

Estimate the SSO volume for record keeping, reporting, and to determine if additional

reporting requirements will be necessary.

Make best effort possible to estimate the spilled volume. There are several methods that can

be used to estimate the overflow volume. The person estimating the spill should make the

best judgment on which method(s) to use.



Some possible methods for measuring the overflow volume include:

1. Duration and Flow Rate: The overflow rate should have been estimated during

assessment of the site, as described above. The overflow volume can be determined by

multiplying the overflow rate by the duration that the overflow occurred.

2. Measuring volume of ponded area or volume captured (volume that cannot be returned

to the sanitary sewer system). Measurements and geometry can be used to estimate the

volume by performing the following:

a. Sketch the shape of the contained sewage

b. Measure or pace off the dimensions

c. Measure the depth at several locations

d. Convert the dimensions (including depth) to feet

e. Calculate the area using the following formulas:

Rectangle Area = length x width

Circle Area = radius squared x 3.14

Triangle Area = base x height x 0.5

f. Multiply area times depth

g. Multiply the volume by 7.5 to convert it to gallons

3. Pump station data may potentially be used if the overflow is from a forcemain or

immediately downstream of the pump station.

Subtract the volume of contained overflow that can be returned to the sanitary sewer system

or properly disposed of.

F. Cleanup

Maintenance staff will perform the following cleanup procedures:

1. Remove and properly dispose of all signs of gross pollution (solids, toilet paper, grease,

etc.).

2. Cleanup Flushing: Flush the affected area with clean water. All flush water should be

contained and subsequently pumped to the nearest sanitary sewer manhole or removed

by vactor truck. Cleanup flushing should be done only with clean, dechlorinated water.

3. Disinfectants should NOT be used due to their toxicity to fish and wildlife.

4. Return spilled sewage to collection system for treatment, when possible.



5. Take digital pictures or video to document conditions after cleanup.

For overflows inside or beneath buildings caused by issues with the sewer main, Contact the

Sewer Maintenance Supervisor. If necessary, TMB Environmental & Loss Management

will be contacted.

G. Receiving Water Sampling

Sampling of Receiving Water is required for Category 1 SSOs in which 50,000 gallons or

greater are spilled into surface waters. Coordinate with Rebecca Ng at the County of Marin

EHS concerning any specific sampling requirements procedures.

1. Sampling will be performed within 48 hours of initial SSO notification.

2. At a minimum, sample sites will include the following:

a. Discharge point in the waterway

b. 100 feet upstream of the discharge point

c. 100 feet downstream of the discharge point

3. Collect samples for ammonia, total and fecal coliform, and enterococcus.

4. Collect at least two (2) samples for each site and label the sample with date, time, and

location.

5. Provide samples to Central Marin Sanitation Agency (CMSA).

6.3 SSO REPORTING

Overflows will be reported in accordance with the requirements of the “Notification

Requirements for SRSD Sanitary Sewer Overflows” and the State of California State Water

Resources Control Board, Order No. WQ 2013-0058-EXEC, included in Appendix C.

Notification and reporting of SSOs to the appropriate regulatory agencies, including the

electronic reporting to the State Water Board, will typically be done by the Sewer Maintenance

Supervisor. In their absence, the Sewer Maintenance Superintendent will perform the required

reporting. Notification and reporting requirements are summarized in the following Table 6-1.

ELEMENT 7 - FATS, OILS, AND GREASE (FOG) CONTROL PROGRAM

The District has adopted the provision of CMSA’s FOG Program. The District and CMSA have

entered into a written agreement; the “Fats, Oils & Grease (FOG) Control Program Agreement”

dated May 10, 2006. This agreement provides for CMSA to develop implement, manage, and

administer a FOG source control program with the District’s service area. A copy of CMSA’s

Conformed Fog Ordinance and the agreement between the District and CMSA is included in

Appendix F.

The goal of the FOG Control Program is to reduce FOG discharged into the sewer collection system,

which will in turn reduce the cost of maintenance associated with FOG and reduce the number of

blockages and SSOs caused by FOG in the sewer system.

The District has identified areas within its collection system that require routine maintenance and

cleaning (i.e. “hot spots). The District routinely cleans and maintains these lines at least twice per

year.

CMSA employs source control to regulate and enforce the regional pretreatment and pollution

prevention programs within its service area. CMSA has designed and implements a customized

computer database program that assists the FOG Control Program. It records and reports Food

Service Establishment (FSE) inspection and compliance, history, generating FSE permits, generating

routine invoices related to the Program, and generating reports as needed to the District.

With the District’s additional effort cleaning hot spots and CMSA’s source control, FOG related

SSOs per year have decreased on average since the time of the FOG Program implementation.

7.1 Public Education and Outreach

The District has made Fats, Oil, and Grease (FOG) refrigerator magnets in both English and

Spanish, and a newsletter in English, Spanish, and Vietnamese, which it has distributed at the

Marin County Fair in recent years. The newsletter and magnets provide information on how to

keep FOG and other materials out of the sewer system to reduce maintenance issues and SSOs.

The newsletter is also mailed to all of customers periodically and is available at:

http://www.cityofsanrafael.org/srsd-news-letters/

CMSA also often provides information to the District’s rate payers on ways to prevent FOG

from entering the sewer system in its monthly newsletter, as well as methods and locations

where fats, oils, and grease can be properly disposed of.

SRSD provides a pamphlet to food service establishments (FSEs) within its service area that

summarizes the California plumbing code grease trap sizing and vent requirements. The District

is also developing a new website to provide a communication link with its rate payers.

7.2 FOG Disposal

CMSA accepts deliveries of FOG from grease traps and interceptors from restaurants, markets,

and similar types of food service establishments. CMSA accepts FOG loads from qualified



haulers with the completion of a simple permit application process, or by special arrangement.

More information can be found within at CMSA’s website, http://www.cmsa.us.

A multi-agency workgroup called CalFog also maintains a list of all agencies within the various

service areas that will accept FOG wastes. This list is available at the following webpage:

http://www.calfog.org/GreaseFacilities.html

7.3 Legal Authority

As previously stated, the District adopted the provision of CMSA’s FOG Program with SRSD

Resolution No 06-930. The District and CMSA have entered into a written agreement; the “Fats,

Oils & Grease (FOG) Control Program Agreement” dated May 10, 2006. The agreement

provides for CMSA to develop implement, manage, and administer a FOG source control

program within the District’s service area. Also, as previously stated, the District’s adopted

Standard Specifications 2007, Part B Section 4-02 and the Standard Specifications for Side

Sewers and Laterals 2007 Section 1-09 prohibit discharge or cause to be discharge of any waters

or wastes which contains more than 100 parts per million, by weight, of fat, oil or grease into its

sewer system.

7.4 Grease Removal Device (GRD) Requirements

The District has identified FOG related “hot spots” at locations in the sewer system where a

FOG related SSO has occurred, where there is significant potential for FOG related SSOs, or

where extra FOG related maintenance is required.

Existing FSEs upstream of “hot spots” are required to obtain a permit with the District and

install and maintain grease removal devices. CMSA regularly inspects and regulates these FSEs.

Existing FSEs upstream of “hot spots” must have grease traps on at least the utensil sink and

dishwasher pre-sink. Drains without traps must be protected by signage and employee training.

Where FOG continues to be an issue downstream of an FSE, the District may require that a

grease interceptor be installed.

The District requires that grease interceptors be installed in all new FSEs. In addition, grease

interceptors are required in all major remodels upstream of “hot spots”. The District considers a

“major remodel” to be significant change to the kitchen and a building permit evaluation of at

least $100,000 (not including grease removal devices). The District requires that grease removal

devices be installed in accordance with Chapter 10 of the Uniform Plumbing Code.

Regulated FSEs are required to clean and legally dispose of FOG in interceptors and large traps

at least every three months, or more frequently if the permit requires. The FSEs are required to

mail cleaning/pumping receipts to the District. They are also required to maintain a copy of

pumping receipts onsite in a District provided folder.

Regulated FSEs are required to clean smaller traps (30 gallons or less) every 15 days. FSE staff

may clean and store FOG in a dedicated drum or tank, to be off-hauled by a registered hauler

monthly.



7.5 Inspection and Enforcement

SRSD Resolution No 06-930 adopting CMSAs FOG Program, and the District and CMSA

written agreement; the “Fats, Oils & Grease (FOG) Control Program Agreement” dated May 10,

2006 gives CMSA authority to inspect FSEs for FOG related issues and enforce violations.

CMSA’s FOG inspections check and verify the following:

GRD maintenance

GRD condition

Grease recycling bins

No prohibited compounds to GRDs

No FOG discharged to drains not connected to GRD

No storm water pollution issues

A. GRD Maintenance

The CMSA inspector reviews the FSE’s documentation, such as cleaning/pumping logs, and

receipts. The inspector physically inspects grease removal devises to verify that the

combined depth of FOG and solids does not exceed 25 percent of the total depth.

B. GRD in Working Condition

The inspector checks traps to verify that flow control devices, vents, baffles, and inlet and

outlet devices are working properly. Interceptors are checked to verify that baffles, inlet and

outlet devices are working properly.

C. Grease Recycling Bins in Use

The inspection verifies that the recycling bin is being used for cooking oil, griddle drainage,

etc, and not for FOG waste from grease traps. The “grey grease” from grease traps should

not be stored in the recycling bins because it is much harder to recycle and costs more to off

haul.

D. No Prohibited Compounds to GRD

CMSA will attempt to verify that no enzymes, solvents, emulsifiers or drain cleaners are

allowed to enter into GRDs. Necessary products may be allowed if authorized in the permit

and with proper documentation.

E. No FOG Discharge to Drain not connected to GRD

Inspection will check for evidence of dumping into peripheral drains (i.e. floor drains, hand

wash sinks). Drains without GRDs should have signs indicating that FOGs should not be



poured down them. Employees should be trained to ensure that dumping of FOG does not

occur into these drains.

Pots and pans should be wiped prior to washing. Food waste should be disposed of into the

trash, not into a garbage disposal. Waste oil should be recycled. Floor mats should be

cleaned over a utility sink with a GRD, wash water should not enter floor drains or into the

storm drain system.

F. No Storm Water Pollution Issues

During inspection, the outside of the restaurant will be checked for potential storm water

pollution issues. If an FSE has potential storm water pollution issues, then a written warning

will be provided. If the FSE fails to resolve the issues, than an administrative citation and

$500 fine will be issued.

If CMSA’s inspection determines that a regulated FSE is not in compliance, then the FSE is

issued a Notice of Violation (a “fix-it ticket”). The FSE is required to pay a re-inspection fee to

CMSA of $200. CMSA then credits the District this amount in its invoice.

The frequency of inspections depends on a facility’s location and compliance history. CMSA

will inspect facilities that are out of compliance or upstream of areas that continue to have issues

with FOG more frequently than facilities that are in compliance and with little or no issues

downstream.

7.6 Identification of FOG Hot Spots

SRSD uses its sewer maintenance application for tracking maintenance activities and linking

them to locations in its GIS system. The District has identified FOG related “hot spots” at

locations in the sewer system where a FOG related SSO has occurred, where there is significant

potential for FOG related SSOs, or where extra FOG related maintenance is required. The

District schedules to clean these areas at least twice per year.

7.7 Development and Implementation of Source Control Measures

The agreement between CMSA and SRSD provides for CMSA to develop implement, manage,

and administer a FOG source control program with the District’s service area.



ELEMENT 8 - SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN

One of the goals of the District’s CIP, that it has prepared and is implementing, is to provide

hydraulic capacity of key sanitary sewer system elements in order to prevent future SSOs. The

District continues to make upgrades to ensure adequate hydraulic capacity in key areas and from the

SSOs that the District has recorded from 2005 to 2014, only one was reported to be caused from

flow capacity deficiency, occurring in 2012.

8.1 Evaluation

The District performed a capacity assessment for four key trunk sewer lines to determine

potential capacity related issues. The Capacity Assessment Report was prepared by Nute

Engineering in April 2010.

The capacity assessment was undertaken using the District’s sewer mapping with surveys of the

rim and invert elevations of trunk manholes, and hydraulic modeling to identify potential

capacity restrictions. The Environmental Protection Agency (EPA) Stormwater Management

Model (PCSWMM) was used to estimate peak flows in these key system components and

hydraulic deficiencies.

8.2 Design Criteria

Design criteria for improvements, including design criteria related to capacity, are included in

the District’s 2007 Standards Specifications.

8.3 Capacity Enhancement Measures & Schedule

The District has incorporated the prioritized recommendations from the Capacity Assessment

Report into its CIP and has already completed many of the high priority and medium priority

projects.

The District’s CIP includes the schedule for its specific capital improvement projects. The

source for funding for these capital improvement projects has been and will continue to be the

service fees and connection fees charged to its users.



ELEMENT 9 - MONITORING, MEASUREMENT, AND PROGRAM

MODIFICATIONS

9.1 Maintenance of Relevant Data

The District uses its sewer maintenance application in MapServer to track maintenance activities

and performance measures. It also tracks and records information pertaining to SSOs and reports

the information to the State Water Board and the Regional Water Board. The District maintains

this data and uses it to prioritize appropriate SSMP actions.

9.2 Monitoring of Implementation and Assessing Success of Preventative Maintenance

The District monitors and measures the effectiveness of the SSMP elements in reducing SSO’s

by developing and tracking performance indicators. The following Table 9-1 lists each SSMP

element, the overall purpose of the SSMP element, and the specific performance indicator that

the District plans to track that will assist in evaluating the effectiveness of the SSMP.

9.3 Updating Program Elements

The District will evaluate elements of the SSMP based on the performance indicators noted in

Section 9.2. Necessary improvements to the SSMP will be documented in the SSMP Audit (see

Element 10). The SSMP and its elements will be periodically updated in accordance with the

results of the District’s Audit.

9.4 Identifying SSO Trends

The data that the District records and reports to the State Water Resources Control Board during

an SSO is used to identify SSO trends. The District also enters the SSO data into its sewer

maintenance application in order to record and track the location of the SSO and other valuable

information. The data that the District monitors and records includes the following:

Number of SSO’s over the past 12 months

Volume distribution of SSO’s (e.g. number of SSO’s greater than 1,000 gallons, 100 to 999

gallons, 10 to 99 gallons, less than 10)

Volume of SSO’s that was contained in relation to total volume of SSO’s

Total volume reaching waters of the State

Total volume not contained but not reaching waters of the State

Cause of SSOs (by percentage of total)

Location of SSOs

Number of SSOs at specific locations

Table 9-2 summarizes the causes of the District’s recorded SSOs from 2005 to 2014.



Table 9-2 – Summary of SSO Causes

Roots and rags are the primary causes for SSOs in recent years, accounting for close to half of

the District’s SSOs from 2011 through 2014. A summary of additional data that the District has

collected for its SSOs from 2005 to 2014 is included in Appendix I.

ELEMENT 10 - SSMP AUDITS

The District will perform an internal audit evaluating the SSMP at least every two years. The audit

will include any deficiencies and steps to correct them. The form included in Appendix G will be

used for the audit, which is based on the format developed by the Bay Area Clean Water Agencies

(BACWA). Upon completion of the audit, the District will keep a copy of the audit on file to fulfill

the Regional Water Board audit requirement.



ELEMENT 11 - COMMUNICATION PROGRAM

SRSD has developed a webpage under the City of San Rafael website, which provides a

communication link between the District and its rate payers. The District has budgeted $10,000 per

year for the public outreach program. As previously stated, the District has made newsletters

available to its users concerning the potential issues caused by FOG and wipes. The District has also

begun outreach to the San Rafael schools by sending a newsletter concerning a growing issue with

rags or “flushable” wipes in the sewer pipelines in the vicinity of schools that can potentially create

blockages. The newsletter specifically targeted the public, private and day care schools, educating

them of the proper handling of the “flushable” wipes. The District has made FOG refrigerator

magnets in both English and Spanish, and a newsletter in English, Spanish, and Vietnamese, which it

has distributed at the Marin County Fair in recent years.

Response Plan The formula used to develop Table A measures the maximum height of the water coming out of the maintenance hole above the rim. The formula was taken from hydraulics and its application by A.H. Gibson (Constable & Co. Limited). Example Overflow Estimation: The maintenance hole cover is unseated and slightly elevated on a 24” casting. The maximum height of the discharge above the rim is 5 ¼ inches. According to Table A, these conditions would yield an SSO of 185 gallons per minute.

Response Plan The formula used to develop Table B for estimating SSO’s out of maintenance holes without covers is based on discharge over curved weir -- bell mouth spillways for 2” to 12” diameter pipes. The formula was taken from hydraulics and its application by A.H. Gibson (Constable & Co. Limited). Example Overflow Estimation: The maintenance hole cover is off and the flow coming out of a 36” frame maintenance hole at one inch (1”) height will be approximately 660 gallons per minute.

Response Plan The formula used to develop Table C is Q=CcVA, where Q is equal to the quantity of the flow in gallons per minute, Cc is equal to the coefficient of contraction (.63), V is equal to the velocity of the overflow, and A is equal to the area of the pick hole.2 If all units are in feet, the quantity will be calculated in cubic feet per second, which when multiplied by 448.8 will give the answer in gallons per minute. (One cubic foot per second is equal to 448.8 gallons per minute, hence this conversion method). Example Overflow Estimation: The maintenance hole cover is in place and the height of water coming out of the pick hole seven-eighths of an inch in diameter (7/8") is 3 inches (3”). This will produce an SSO flow of approximately 4.7 gallons per minute.


2 Velocity for the purposes of this formula is calculated by using the formula h = v squared / 2G, where h is equal to the height of the overflow, v is equal to velocity, and G is equal to the acceleration of gravity.

V. PUBLIC NOTIFICATION:

Signage:

SRSD maintains an inventory of Raw Sewage Warning signs and barricades for posting

at recreational areas or locations where the public may potentially contact wastewater that

was spilled into the storm drain system, drainage channels, creeks, storage ponds, or

lagoons downstream of the spill. Document where signs are placed so every sign can be

retrieved after cleanup. Signs are kept in the lower shelf in the black file cabinet next to

the TV in the maintenance shop. Coordinate with Rebecca Ng at the County of Marin

EHS as to exact placement of the signs. Also ask Rebecca Ng whether or not the press

needs to be notified of the spill. If the press needs to be notified, contact the District

Manager/District Engineer, Doris Toy at the above numbers.

The District Manager/District Engineer will contact the Board members and the City of

San Rafael, Department of Public Works for Category 1 SSOs.

VI. SAMPLING

1) Collect samples for ammonia, total and fecal coliform, and enterococcus.

2) Collect two (2) samples for each site and label the sample with date, time and

location.

3) Sample sites are as described:

a. Discharge point in the waterway

b. 100 feet upstream of the discharge point

c. 100 feet downstream of the discharge point

4) Coordinate with Rebecca Ng at the County of Marin EHS as to any other

samples that need to be taken.

5) Take the set samples to CMSA.

ESTIMATING SSO VOLUME

There are a variety of approaches for estimating the volume of a sanitary sewer overflow.

Here are three (3) methods that are most often used. Use the method that is most

appropriate for the sewer overflow in question and the best information available.

Method 1: Eyeball Estimate

This method can be useful for small spills up to 100 gallons. To use this method,

imagine the amount of water that would spill from a bucket or barrel. A bucket contains

5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to

break the standing water into barrels and multiply by 50 gallons.

Method 2: San Diego Reference Chart

Review the attached chart. This method can be used for spills up to 275 gallons per

minute. To use this method, estimate flow based on what the reference sheet has

depicted in each of the nine (9) pictures provided.

Method 3: Measured Volume

Most small spills can be estimated with this method. The shape, dimensions, and depth

of the spilled wastewater are needed. The shape and dimensions are used to calculate the

area of the spill and depth is used to calculate the volume:

1. Sketch the shape of the contained sewage

2. Measure or pace off the dimensions

3. Measure the depth at several locations

4. Convert the dimensions (including depth) to feet

5. Calculate the area using the following formulas:

Rectangle Area = length x width

Circle Area = radius squared x 3.14

Triangle Area = base x height x 0.5

6. Multiply area times depth

7. Multiply the volume by 7.5 to convert it to gallons

Reach surface water and/or reach a drainage channel tributary to a surface

water; or

Reach a Municipal Separate Storm Sewer System (MS4) and are not fully

captured and returned to the sanitary sewer system or not otherwise captured

and disposed of properly. Any volume of wastewater not recovered from the

MS4 is considered to have reached surface water unless the storm drain

system discharges to a dedicated storm water or groundwater infiltration basin

(e.g., infiltration pit, percolation pond).

CATEGORY 2

Discharges of untreated or partially treated wastewater of 1,000 gallons or greater

resulting from an enrollee’s sanitary sewer system failure or flow condition that do

not reach surface water, a drainage channel, or a MS4 unless the entire SSO

discharged to the storm drain system is fully recovered and disposed of properly.

CATEGORY 3

All other discharges of untreated or partially treated wastewater resulting from an

enrollee’s sanitary sewer system failure or flow condition.
